Abstract
Keeping the oil return path of rotary distributor under a certain back pressure can improve the working life. The formula of flow, pressure, loading capacity and oil film stiffness in gap flow field is derived in this paper, the variation characteristics of fluid in the gap flow field is obtained when the back pressure increases, and then the finite element analysis of gap flow field is adopted with Fluent to verify the theoretical formula. The conclusion is that the back pressure can be properly increased while the variable load of rotary distributor is satisfied.关键词
